We all swooned when Eugenie stepped out in her stunning Peter Pilotto wedding dress in front of St George's Chapel ahead of her nuptials to Jack Brooksbank.
Then, the blush Zac Posen dress she donned at the evening reception took our breath away.
But there was a third look from the royal bride to celebrate her big day that we didn't see, and this one might just take the cake out of all three.
The Princess wore a pale pink biker jacket with the words 'Mrs Brooksbank' embroided on the back for the second day of her wedding celebrations, and we're pretty sure she would have looked the image of cool in it.
Sharing an image of the emblazoned jacket on Instagram, the designer, Sam Dougal wrote: "I'm so so honoured to have been asked to design the bespoke look she wore for the day 2 wedding celebrations at Windsor in collaboration with her brilliant stylist @styletonic_sarahprice."
He revealed the handwriting on the jacket was actually the princess's own, which added a special touch.
The jacket itself was made out of silk crepe according to Harper's BAZAAR UK, and the style, which was worn with a white mini-dress, defied conventional royal traditions.
Dougal said the outfit was a reflection of the "fun and informality" of the second-day event's festival theme.
"The look is an exciting and unusual one for a royal wedding, and had to go with the feel of the day," he told Harper's BAZAAR UK.
"Much like Eugenie, the look is totally unique, and full of fun. It's a simple party dress with a modern jacket."
Eugenie worked with Dougal and her long-standing stylist Sarah Prince to perfect the look, ultimately deciding to incorporate tradition by choosing a white dress for her third look of the festivities.
"You only get married once and Eugenie wanted to stay with white for the weekends celebrations," Dougal explained.
"The addition of a pale pink jacket moves it forwards into day one of her marriage, especially with what is written in embroidery on the back." WATCH: Princess Eugenie and Jack Brooksbank seal their wedding with two kisses!Story continues below...
Dougal is no stranger to the newlywed royal - he designed her powder blue 60s-esque dress she wore to Harry and Meghan's wedding back in May.
While we're yet to see a picture of Eugenie in the jacket and mini-dress in full, we can picture how incredible the bride must have looked.
There was no denying the royal wedding was a lavish affair, with not one but three parties for guests to celebrate the long-term couple's nuptials.
A-list guests took to social media to share some of the festivities - designer Stella McCartney added a picture of Demi Moore during the lunch time reception on Friday at Windsor Castle's St George's hall.
The event was followed by an evening reception at Royal Lodge Windsor. The following day, a slightly less formal event was held in the grounds of Royal Lodge Windsor.
The fun and frivolous event, where Eugenie donned her biker-jacket and mini-dress ensemble, included a carousel and a gorgeous setting of ivy, florals and fair-themed games.
Actress Cleo Von Adelsheim and Irene Forte shared some candid pics from inside the grounds.
